Questions tagged [tic-tac-toe]

Tic Tac Toe is a popular exercise for beginning coders, as the finite resources and game mechanics can be easily grasped and represented in many ways. As it is a short game, it is possible to create an algorithm that never loses.

The X player usually goes first. The player who succeeds in placing three respective marks in a horizontal, vertical, or diagonal row wins the game. The following example game is won by the first player, X.
